Bag web and method for packing a product in film bags by using such a bag web

Abstract

There is disclosed a bag web for packing articles in film bags provided as a contiguous web. At an opening edge, the bag web is provided with peripheral strip areas having holes intended for guide connection with guide means that can retain and guide the bags along a conveyor path through a filling station. The bag items will thus be contiguous along an upper edge, which is used for guiding. The bag webs include the film webs forming opposing front and back sides of the bag and additional film pieces disposed between the flat sides of the bag in order thereby to form side or bottom, or both side and bottom, of the bag. By such a bag web is achieved a particularly simple and rapid filling of the type with stand bottom and with folded side edges.

Description

[0001]This application claims the benefit of Danish Application No. PA 2014 70406 filed Jun. 30, 2014, and PCT / DK2015 / 050193 filed Jun. 30, 2015, International Publication No. WO 2016 / 000718, which are hereby incorporated by reference in their entirety as if fully set forth herein.FIELD OF THE INVENTION[0002]The present invention concerns a bag web for packing articles, liquid or loose material in film bags that are provided in a contiguous web of bag items, wherein the bag web along its opening edges includes peripheral strip areas prepared with a series of holes or corresponding star perforations intended for guide connection with guide means, which are arranged for retaining and guiding peripheral areas at the opposing bag opening edges along a conveyor path through a filling station, the bag web being of the type consisting of a contiguous series of bag items separated by a number of slits that extend from a bottom edge of the web up to a point below an upper edge of the web.[00...

AI Technical Summary

Benefits of technology

The invention is about a method and bag web for packing products in film bags. The bag web is a continuous web that is conveyed through a filling station, allowing for a high filling rate. The invention also provides a cost-effective way to produce the bags and achieve a high filling rate.

Problems solved by technology

This is of substantial significance in that as a basic material a simple rolled op flat film web without local thicknesses may be used, however in return there are considerable problems with regard to both the guidance of the opposite edges of the bag items for a safe engagement with the chains and with regard to a desirably inexpensive embodiment of these chains.

This engagement, however, is not more firm than axial slipping may occur between the upper edges of the bag web and associated belt conveyor means, whereby uncertainty may arise as to whether a conveyed item has been conveyed entirely synchronously with the conveyor belts.
